LEONHARD BAUROTI-I, 0F TOLEDO, OHIO, ASSIGNOR TO THE METALLIC BARRELCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.

BARREL-SIZING AND CRIMP-ROLLING MACHINE.

To all whom it may concern:

Be it known that I, LEONHARD BAUROTH, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Barrel-Sizing and Crimp-RollingMachine; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to the manufacture of sheet-metal packages, andparticularly to those of the type which are longitudinally crimped inthe body forming operation, but the invention is not restricted to suchuse as it may be employed in any connection for which it may be adaptedor appropriate. In the manufacture of metallic packages of this classconsiderable difficulty is experienced due to the diiference in thetempering of different sheets of metal, whereby some are of a moreresilient nature than others. The principal difficulty from this causearises in the manufacture of ribbed or crimped packages, as it is foundthat the packages when they come from the ribbing or crimping machinesvary greatly in diameter, some being under and some over size. It istherefore necessary to subsequently act on the packages in some mannerto make them of uniform size.

The primary object of my invent-ion, is the provision of a simple andefficient machine which will act on ribbed or crimped packages touniformly size the same, and at the same time roll over or flatten thecrimps or ribs at the package ends to fix such ends against contractionor expansion when taken from the machine and to adapt the ends for theinsertion of the usual end closure.

The invention is fully described in the following specification, and apreferred embodiment thereof illustrated in the accompanying drawings,vin which,

Figure l is a side elevation of a machine embodying the invention withportions of the same in section. Fig. 2 is a section of the same on theline a: m in Fig. 1. Fig. 3 is a detail of the work supporting cradle.

Serial No. 550,231.

Fig. 4 is an enlarged section of a portion of the work-chuck or holder,and Fig. 5 is a diagram of the rolls acting on a blank.

Referring to the drawings, 1 designates the base or bed of the machine,which is shown in the present instance as provided 011 its top with thelongitudinally-extending ways or guide-ribs 2, 2 on which the adjustablesuperimposed parts rest, and at its upper side edges with thelongitudinally-extending horizontal flanges 3.

Rising from one end of the base 1 is a standard 4, in the lower portionof which is journaled one end of a shaft 5. The other end of such shaftis j ournaled in a bearing 6 at the o oposite end of the base andcarries a pulley 8 designates another standard, which is mounted uponthe ways 2, 2 for adjustment longitudinally of the base toward and awayfrom the standard 4. Screwheld clamping plates or fingers 9 are carriedat the lower side edges of the standard 8 for engaging under the baseflanges 3 and cooperating therewith to secure such standard in adjustedposition.

Carried in advance of the standard 8 by pins or other suitable carryingmeans 10 projecting therefrom is a ring member 11, the opening of whichis fashioned to conform to the desired shape of the end or ends of thework to be acted on. The interior of the ring 11 is reamed out orenlarged from its outer edge inwardly for a suitable distance, asindicated at 12, and in this is first mounted a thrust ring 13 inabutment with the shoulder at the inner end of such on largement andthen a rotatable bushing member 14. This bushing is permitted to rotatefreely within the ring 11 due to the provision of a series of rollerbearings 15 between it and the thrust ring 13, as best shown in Fig. 4,and is held against outward displacement by the headed ends of screws 16or other suitable means carried by the ring 11. The rings 11, 13 andbushing 14 combine to form what may be termed a chuck for receiving" andtruing ends of metallic packages such as barrels, and as it is intendedmore particularly for use in connection with bilged barrels, itsinterior surface is tapered from end to end to conform to the endformation of such articles. When an end of a barrel is forced within thechuck as hereinafter described its edge portion or as having one endjournaled in the standard 4 and its other end journaled on athrustbearing 24, projecting from the standard 8. The rolls 17, 17 workwithin an incut 25 in the ring 11 of the work-chuck and are adjustablyand yieldingly held together or in contact with the interposed metal bya handscrew 26, which is carried by the standard 8, and acts on a plate27 between which and the associated upper bearing-block 19 is disposed asuitable yielding substante 28, such as rubber.

29 designates a cradle, which is suitably fashioned to provide a seat orsupport for the endportion of the work opposed to that being operatedon. This cradle is mounted for longitudinal adjustment on theways 2, 2and carries clamping-plates 30 at its ends for engaging under the baseflanges 3 to secure it in adjusted position to the base. Thew-ork isforced into position within the chuck 11-14 by a thrust plate or member32, which is flanged as at 33, to fit over the end of the work and iscarried by a hand-screw 34. This hand-screw is horizontally disposed andthreads through a standard or carrying block 85, which is suitablysecured for longitudinal adjustment on the ways 2 by clamps 35 engagingthe boss flange-3.

' In Fig. 5, 36 designates a portion of the end of a metallic barrel orpackage, and 37 the longitudinal crimps of the same, which are shown at38 as being rolled flat to the body end by the action of the rolls '17.

In the use of my invention, a barrel or the like is placed with one endprojected into the chuck 11-14 and its other end portion resting on thecradle 29. If the barrel is oversize the hand screw 34 is operated tomove the plate or member 32 to bear on the outer barrel end and to forcethe barrel into the chuck to effect a closing of the crimps, whichspring partly open after a forming of the same, and a contraction ofsuch end of the barrel. This forcing operation is continued until theedge or chime of the barrel has been projected the desired distancebetween the working faces of the rolls 17 when the screw 26 is turneddown to give the rolls the desired pressure on the workto flatten theend port-ions of' the crimps-or ribs 37 thereof. Upon a setting inmotion ofthe mechanism-driving the rolls 17 the work is caused to rotatewithin the chuck, the bushing 14 permitting a free turning of the same,and the rolls act on the crimp ends to flatten the same and thus fix thebarrel end in the shape to which it is drawn. The rolls also act tostraighten or remove the taper from the chime portion of the work tofacilitate an insertion and tight fitting of an end closure therein. Theclamping-plate 32 also turns with the work, being swiveled on the screwend for such purpose. In treating an undersize barrel it is notnecessary to operate the screw 34 to force it within the chuck, as itfits loosely therein, but such screw is operated to place its thrustmember 32 in contact with the outer work end to hold the same inposition while being acted on. Upon a tightening of the rolls 17 uponthe work end and a setting in motion of the same the end portions of theribs are flattened and the work end expanded to fill the chuck and toassume the desired size, in which expanded state it it fixed by therolling of the crimp ends.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of the parts except in so far as such partsare specified in the claims.
